  • the emission portion 64 is formed of a transparent member that transmits light at one surface of a light source box 65 having an approximately rectangular parallelepiped-like shape. With the light guide plate 63 and the emission portion 64 facing each other, the instrument for an endoscope is irradiated with the ultraviolet rays UV that are emitted through the emission surface 63 b of the light guide plate and that pass through the emission portion 64 .
  • the ultraviolet ray source 60 is any of an excimer lamp or a light emitting diode (LED) for ultraviolet rays.

  • the transmittance of the first ultraviolet rays with respect to a living body is lower than the transmittance of ultraviolet rays (specific ultraviolet rays) at a wavelength of 254 nm (at which the intensity of light is high) with respect to a living body.
  • the transmittance of the first ultraviolet rays with respect to a cornea of an eye is 0.01 and the transmittance of the specific ultraviolet rays with respect to the cornea is 30%. Therefore, the first ultraviolet rays have an ability for sterilization and inactivation of viruses, which is inherent in ultraviolet rays, while being safe for the skin and eyes of humans and animals.
  • the ultraviolet rays are invisible light that cannot be recognized by a human, a visible light source may be separately provided so that visible light such as blue light is emitted. In this case, the visible light may be adjusted in density over time or may be turned on and off slowly.
  • the LED for ultraviolet rays emits second ultraviolet rays, which are deep ultraviolet rays having a wavelength range of 300 nm or less, as ultraviolet rays. Since the second ultraviolet rays have a function of destroying genetic information of a virus or a bacterium, the second ultraviolet rays have a sterilization effect on water, air, or the like. For example, the second ultraviolet rays have a high sterilization effect against the human coronavirus (HCoV-229E), as a virus. In addition, it is preferable that the LED for ultraviolet rays has a function such as a waterproofing function or a heat radiation function. The influence of the LED for ultraviolet rays on the environment is smaller than that of a mercury lamp.

  • the ultraviolet ray source unit 53 may be attached to the processor device 15 to irradiate the processor device 15 with the ultraviolet rays UV. In addition, it is preferable that the ultraviolet ray source unit enters an in-use state in which irradiation with the ultraviolet rays is performed in a preparation stage before endoscopy or a test-ended stage after the end of the endoscopy.
  • the ultraviolet ray source unit 53 may be attached to a side surface 70 a of a cleaning and disinfecting apparatus 70 .
  • the cleaning and disinfecting apparatus 70 includes a storage portion 71 in which an endoscope is stored and cleaned or disinfected, a lid 72 used to airtightly close the storage portion 71 , and an operation panel 73 used to perform an operation such as a cleaning start operation.
